Answer:
A=72
Step-by-step explanation:
72-2/7 = 10
72-2=70
7X10=70
It states your "X" will be zero when solving for "Y".
So when solving for "Y" your equation would be;
0+y=4
Then you solve. Y=4
Then you do the same with the "X":
X+0=4. Then you solve. X=4
It would end up being (4(x),4(y) )
Then do the same for the next problem.
1) Zoe's town
April = 5 7/8 inches
May = 2 1/8 inches less than in April
5 7/8 ⇒ ((5*8)+7)/8 = 47/8
2 1/8 ⇒ ((2*8)+1)/8 = 17/8
47/8 - 17/8 = 30/8 ⇒ 3 6/8 ⇒ 3 3/4 inches rainfall in May.
April rainfall : 5 7/8 inches
May rainfall : 3 3/4 inches
